Part 1:
Plan 1: y = 25x
Plan 2: y = 120 + 10x
x = number of weeks
y = total money
Part 2:
Plan 1 requires 8.8 weeks.
220/25 = 8.8
Plan 2 requires 10 weeks.
220 - 100 = 100
100/10 = 10 weeks
Plan 1 is best since the money is earned faster.
Answer:
Max: Victor: Roman
6: 3: :9
Step-by-step explanation:
Max: Victor: Roman
3 : 2 : 4
Take away 1/4 of 2
1/4 of 2 =
1/4*2 = 1/2
2-1/2 =
4/2 - 1/2 = 3/2
Victor now has 3/2
Roman gets 1/2 so he has
4+ 1/2
8/2 + 1/2 = 9/2
Max: Victor: Roman
3 : 3/2 : 9/2
But we normally don't leave fractions in the ratio's
Multiply each number by 2 (the ratio won't change)
3*2 : 3/2*2 : 9*2
6: 3: :9
Answer:
I cant do them all for you, but essentially every equation there is an a, plug in 10 for a. Every equation with b, plug in 9 and every equation with c plug in 4. Then Solve/simplify
Step-by-step explanation:
Answer:
Step-by-step explanation:
The first step you want to do is get one variable by itself. We are going to start by isolating y by itself.
-3x + 9y = -27
9y = 3x - 27
y = 1/3x - 3
By isolating y by itself, you now have a function written in slope-intercept form. To graph this function, you can draw a point at (0,-3), then use rise/run to go up 1 unit and over 3 units to the next point (3,-2). You can then draw a line based on this information.
